STRUCT RPPX1_AWBG_PARAMS(9)

💅 struct rppx1_awbg_params(9) 💅

okay bestie, this one is straight from the Kernel API Manual, and it's giving white balance, but make it kernel struct. no cap, it's lowkey iconic. 💖

✨ NAME ✨

struct rppx1_awbg_params — WB gain configuration. that's the whole vibe, periodt.

---

🎀 SYNOPSIS 🎀

struct rppx1_awbg_params {
    struct v4l2_isp_params_block_header header;
    __u32 gain_red;
    __u32 gain_green_r;
    __u32 gain_blue;
    __u32 gain_green_b;
 };

---

🧩 Members 🧩

• header — block header (type = RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE1 or type = RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE2 or type = RPPX1_PARAMS_BLOCK_TYPE_AWBG_POST)
• gain_red — gain for red component, 18-bit (unsigned Q6.12)
• gain_green_r — gain for green component in red lines, 18-bit (unsigned Q6.12)
• gain_blue — gain for blue component, 18-bit (unsigned Q6.12)
• gain_green_b — gain for green component in blue lines, 18-bit (unsigned Q6.12)

🌸 Description 🌸

so the RPP-X1 White Balance Gain module is available in the PRE1 and PRE2 pre-fusion pipes and in the MAIN_POST post-fusion pipe. userspace selects which pipe to operate by setting the header.type field to RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE1, RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE2 or RPPX1_PARAMS_BLOCK_TYPE_AWBG_POST. slay. 💅

the White Balance module allows you to specify per-color channel gains, expressed as unsigned fixed-point values as 18 bits unsigned integers in Q6.12 format with a maximum of 63.999. that's the math, bestie, and it ate. 🔥

made with love from the Kernel API Manual, source ./include/uapi/linux/media/dre..., dated October 2026, and yes we're closing with struct rppx1_awbg_params(9) because main character energy demands it 💜✨🎀
